Specification forming part of Letters Patent No. 36,755, dated October21, 1862.

To all whom it may concern:

Be it'known that I, GEORGE L. WITSIL,

of the city of Philadelphia, in the State of Pennsylvania, have inventeda new and useful Improvement in Burners for Goal-Oil Lamps; and I dohereby declare that the following is p a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to theaccompanying drawings, making a part of thisspecification, in which Figure 1 is a side elevation; Fig. 2, a planView, and Fig. 3 a central vertical section showing the wick applied,like letters indicating the same parts when in the different figures. Y

The object of this invention is the production of a burner for coal-oillamps that will serve effectually in the combustion of the oil, so as toproduce therefrom withonta chimney, a larger and brighter smokelessflame, and at the same time better protect the flame frombeingextingnished by currents of air produced in'lifting and carryingthe ignited lamp about, or otherwise.

It consists of two flat tapering air-flues arranged so as to be inclinedtoward each other at their upper ends and afford a large taperingwickchamber between, in combination with two deflectors curving over theupper endsof the said air-fines, respectively, and extending laterallybeyond them on each side, the whole being constructed and arranged inrelation to the supportingcap substantially in the mannerhereinafterdescribed and specified.

In the drawings, A A are the two air-flnes; B, the wick-chamber; a a,the two deflectors, and G the supporting-cap.

The air-flnes A A are each formed of thin plate metal,and securedtogether between two flat supporting-plates, d d, so as to produce aninclined tapering passage way for discharging air on each of the twoflat sides only of the upper end of the wick b, which projects a littleabove the said fines, the length of the upper opening of each flue beingequal to the length of the upper opening of the wick-' space B between,while the lower ends of the air fines A A open on the outside of thewick-chamber B, and the latter extends down ports the whole, as seen inFig. 3, so that it will open into the bowl of the lamp to which it maybe applied, the usual wick-adjusting device, b being applied so as toserve as a means of raising and lowering the wick.

The deflectors a a are cut out of thinmetal plate, bent into the curvedforms and applied so as to project toward each other over the upper endsof the flues A A, as represented in the drawings-i. e.,.soas to presenttwo plates curved toward each other and extending in length horizontallyabonta quarter of an inch beyond the two opposite narrower sides of thetwo flues A A, and so as to leave a space, c of about three-sixteenthsof an inch'wide be tween their approaching edges, the space between theflnes which forms the outlet for the wick b being about one-eighth of aninch wide and about a quarter of an inch below the up per edgesof thedeflectors, substantially as seen in Figs. 2 and 3. a

In the operation of this burner, while th wick b conducts the oil up toits upper end, the upper ends of the fines A A, and thedeflecting-plates a a become heated, and conse quently they warm thethin flat currents of I air which passin contact with them and discharge it into the flame, thus affording a copious supply of warm airthereto, and effecting the combustion of the carbonaceous matter of theoil, so as to produce a large, bright, and smokelessflame,.substantially of the size and form indicated by the dotted linefin Fig. 1; and at the same time if the lamp be moved about, suddenlylifted, or otherwise subjected to currents of air, the deflectors aawill pre vent the extinguishment of the flame by directing the currentswith 'the flame, either downward through one or both of the flues A A,or longitudinally along beneath the deflectors, as the direction of theapproach of the draft of air may be. The wick-chamber'being roomy, thewick is not liable to be charred nor even heated below the flame.

The whole construction is believed to be more simple, cheap, andeflectivefor the purpose than any other bnrner in use for burningcoal-oil without a chimney.

Having thus fully described my improved burner, and pointed out itsutility, what I" other and the cap 0 substantially in the manclaim asnew therein, of my invention, and dener described and set forth, for thepurposes sire to secure by Letters Patent, isspecified.
